Description

The Neumann KH 420 3-Way Active Studio Monitor is designed for those who demand nothing less than exceptional audio precision. Whether you're engaged in music production, mixing, mastering, or broadcasting, this powerhouse of a monitor delivers an impressively natural and clear sound. Its tri-amplified system powers each driver individually, ensuring impeccable sound reproduction across the entire frequency spectrum.

Thanks to its Mathematically Modeled Dispersion (MMD) waveguide, the KH 420 ensures an even sound distribution, minimizing unwanted reflections and providing a stable listening experience within its optimal range of 5–9 feet. The narrower vertical dispersion further refines this focus, making it a perfect fit for professional studio environments. With a remarkable sound pressure capacity of up to 122.4dB and a bass response reaching as low as 26Hz, it captures every nuance with stunning clarity and depth.

Constructed from Low Resonance Integral Molding materials, this monitor's cabinet design reduces resonances and intermodulation distortion, allowing the unique fabric dome to shine in the midrange frequencies. With optional digital input modules available, the Neumann KH 420 adapts effortlessly to modern studio setups, offering digital connectivity and delay options.

Critic Reviews

Neumann KH420

soundonsound.com

The Neumann KH 420s deliver stunning transparency and precision, elevating the benchmark for active studio monitors. With impressive low-distortion drivers and comprehensive room EQ options, these monitors excel across all genres, revealing the subtleties in recordings without harshness. However, they come with a hefty price tag, and while they are marginally more affordable than their predecessors, they remain a significant investment. If you're after high-end performance and are willing to spend, the KH 420s are an exceptional choice, but budget-conscious buyers may want to explore alternatives.

Used to mix the The Magnificent Seven soundtrack, as stated in this October 20, 2016 Audio Media International article.

We looked at the options and decided, having built guerrilla studios in the past, that mixing at home was possible. There we used Neumann KH420 mid-fields, each sitting on top of Neumann KH870 subwoofers for an amazing 7.1 rig combination. We then used KH310s for the sides and surrounds.

Avatar was the last film that we mixed in analogue as a crew but since then everything has been entirely in the box. I used an Avid C24 as a mix controller and was taking sounds that the live players were generating and manipulating them through Pro Tools. I used quite a lot of plug-ins, including [The Cargo Cult] Slapper for multi-channel delay and the VSM plug-ins, which I really like. We needed a bit of a contemporary sound so we also used a whole host of different reverb plug-ins along with delay and compression.
